IMPROVEMENT IN CRIMPING-FORMS.

Specification forming part of Letters Patent No. 202, 123, dated April9,1878; application filed October 2, 1877.

To all whom it may concern:

Be it known that I, JAMES RYAN, of Honesdale, in the county of Wayne andState of Pennsylvania, have invented a new and useful Improvement inCrimping-Forms; and I do hereby declare that the following is a full andexact description of the same, reference tacks employed, and at the sametime will be convenient in use; and my invention therein consists,mainly, in providing the crimper at the points where it is desired tosecure the leather thereto with a number of metallic plates, havingholes or sockets to receive the tacks and hold the leather in position;and, further, in the construction of the said plates, as fullyhereinafter explained.

To enable others skilled in the art to manufacture my crimper, I proceedto describe the same, having reference to the drawings, in which- Figure1 is a perspective view of the crimping-form, showing a single tack inposition; and Fig. 2, a separate view of the plates forming thetack-holes.

Like letters denote corresponding parts.

A is a crimping-form, made of wood, in the ordinary shape. At the pointswhere it is customary to drive the tacks into the form I place a pairofmetallic plates, B B, having coincident grooves a a on their innerfaces,

which, when placed together, make tack-holes 13 B are secured together,and to the back of the leg-section and the foot of the crimper, bywood-screws c, passing directly through the plates into the crimper.

The inner edges of the plates are beveled off, as shown by b, so as toguide the tacks into the holes. The plates B B being situated on theback of the leg and on the under side of the foot of the crimper, theywill set flush on each side of such crimper, and are adapted to receivetacks on each side.

When the boot-upper is stretched on the form, the steel tacks G aredriven through the leather on each side of the form and into the holesI). These holes will keep the tacks perpendicular to the sides of theform, and will prevent the leather from slipping from the position inwhich it is first tacked.

My crimping-form possesses many advantages over the ordinaryform, aswill be readily seen from inspection, it being more durable, (in theordinary crimper the repeated driving of the tacks into the wood soonwears out the crimper,) holds the leather more securely, makes a savingin steel tacks, since a very small number are bent, and permits thetacks to be driven and withdrawn easier and in a more expeditiousmanner.

Having thus fully described my crimper and explained some of itsadvantages, what I claim as new therein, and desire to secure by LettersPatent, is-

1. A crimping-form for boots having metallic plates provided with holesor sockets, into which the tacks are driven to secure the leatherthereon, substantially as described.

2. The combination, with the crimping-form A, of the grooved metallicplates'B B, substantially as described and shown.
